Dax rolled over!

He's been able to roll over from his back to either side and then from side to his stomach... for nearly a month. However, yesterday, he rolled over from his stomach onto his back! And I missed it. I walked back into the room a minute later and he was magically on his back instead of on his stomach on his little floor mat.

I'm very curious as to how he did it. Especially since I've seen him roll from his back onto his side, and it isn't the typical way a baby rolls. Dax rolls using his legs. Specifically, he uses his legs to create momentum and thrust his body to the side. It's adorable.
